Codex Skill

Bridge to the OpenAI Codex CLI for high-reasoning tasks using gpt-5.3-codex.

Features

1. High Reasoning: Leverages gpt-5.3-codex with configurable reasoning effort (default: high).
2. Structured Output: Supports JSON Schema for guaranteed output shapes.
3. Automatic OAuth: Uses the existing codex CLI authentication.
4. Sandbox Aware: Runs within the Codex sandbox policy if requested.

Usage

Simple Reasoning

./run.sh reason "Explain the relationship between CAPEC and ATT&CK"

Structured Extraction

./run.sh extract "Find all entities in this text" --schema entities.json

Direct CLI Access

# Pass prompts via stdin for complex multi-line tasks
echo "Analyze this code" | ./run.sh exec --model gpt-5.3-codex

Integration with Dogpile

The dogpile skill uses this skill for:

1. Ambiguity Checks: High-reasoning analysis of user intent.
2. Synthesis: Consolidating search results from multiple sources into a coherent report.
